Well first off, this isn't a funtoo or debian forum so I'm not sure if we can help you.

Having said that you clearly know how to do package installs, have you installed portage?

If so I recommend the next step being an install of: app-portage/eix
This is a package tool that will help you in searching for the specific packages you want. Once it is setup you can use commands such as eix -S "firefox" to see the firefox packages for example. This will help you in searching for the available items.

As to specific Gnome versions I am not sure._________________Linux, the OS for the obsessive-compulsive speed freak in all of us.
